If you enabled these extensions:
2 . Query device for pointers to following 2 extension functions, using
`vkGetDeviceProcAddr()`. Pass them in structure VmaVulkanFunctions while creating
your `VmaAllocator`.
- `vkGetBufferMemoryRequirements2KHR`
- `vkGetImageMemoryRequirements2KHR`
Other members of this structure can be null as long as you leave
`VMA_STATIC_VULKAN_FUNCTIONS` defined to 1, which is the default.

your `VmaAllocator` to inform the library that you enabled required extensions
and you want the library to use them.
